Polymerizable organosilane compound

Abstract

A novel organosilane compound having polymerizability is disclosed which is a vinyl ω-triorganosilyl n-undecanoate of the formula CH 2 ═CH--O--CO--(--CH 2 --) 10 --SiR 3 , in which R is an alkyl group having 1 to 4 carbon atoms, alkoxy group having 1 to 4 carbon atoms or trialkyl siloxy group of which the alkyl group has 1 to 4 carbon atoms. This compound can be prepared by the hydrosilylation reaction between a triorganosilane of the formula HSiR 3 and vinyl 10-undecenoate of the formula CH.sub.2 ═CH--O--CO--(--CH.sub.2 --).sub.8 --CH═CH.sub.2 in the presence of a platinum catalyst. The compound is polymerizable to give not only a homopolymer of the compound alone but also a copolymer with other comonomers such as vinyl chloride, chloro trifluoroethylene, methyl methacrylate and the like.

What is claimed is: 
     
       1. A vinyl ω-(triorganosilyl) n-undecanoate represented by the formula   CH.sub.2 ═CH--O--CO--(--CH.sub.2 --).sub.10 --SiR.sub.3,     in which each R is a member of the group consisting of monovalent hydrocarbon groups of 1 to 4 carbon atoms, alkoxy groups of 1 to 4 carbon atoms and trialkyl siloxy groups of which each alkyl group is of 1 to 4 carbon atoms.   
     
     
       2. Vinyl ω-(trimethylsilyl) n-undecanoate. 
     
     
       3. Vinyl ω-(methyl diethoxy silyl) n-undecanoate. 
     
     
       4. A compound of claim 1 wherein at least one R is methyl.
